Scrambled console output has shown up on a Pi3 under what might be called overload conditions, things like make -j8 buildworld and running of stress2's default test suite. It doesn't seem to be a serial issue in that case. Hard to believe you're seeing something related, but my $.02 anyway. bob prohaska ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

I’m using Serial-Over-LAN via ipmi/drac and am noticing this too on a Dell C6220, don’t know when this started though, It’s only recently that I’m working on this kind of hosts. It drives the xterm/rxvt crazy, but it’s only the output from the boot/loader, once the kernel takes over, all is back to normal. the serial speed is set to 115200, but changing it as far as i remember did not help. will try lowering soon. I had to disable the menu to get some sense of the output, and usually have to hit ^B to remove most of the garbage. ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
zfsloader: messy output on Dell iDrac serial console
running on *some* Dell servers the serial console looks messed up at the time of the FreeBSD menu. it looks like it's dropping (or adding? but that's less likely) characters. | 5. [K]ernel: kernel (1 of 2) | .- . -. | 6. Configure Boot [O]ptions... |2 --| y/ -. -/` -o/ |137. Select Boot [E]nvironment... | `:` `:` ::/sy++:. | H| .-- `--. -- /6H`: :` | | .---.. IS there an RTS/CTS input we should be attending to? I will add that some of the other modules (e.g. the mfi raid setup section) also get affected, so it's not just a bug in our code. ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
